Updating ``Medical radar signal dataset for non-contact respiration and heart rate measurement" with expanded data on laboratory rats under isoflurane anesthesia.

The dataset presented in this article is an update of the dataset provided by K. Edanami and G. Sun entitled "Medical Radar Signal Dataset for Non-Contact Respiration and Heart Rate Measurement" [1].

Magnetic and Transport Properties of New Dual-Phase High-Entropy Alloy FeRhIrPdPt.

High-entropy alloys (HEAs) are broadly explored from the perspective of mechanical, corrosion-resistance, catalytic, structural, superconducting, magnetic properties, and so on. In magnetic HEAs, 3 transition metals or rare-earth elements are well-studied compositional elements. We researched a magnetic HEA containing Fe combined with 4 and 5 transition metals, which has not been well investigated, and found a new dual-phase face-centered-cubic (fcc) HEA FeRhIrPdPt.

Explainable Deep Learning Reproduces a 'Professional Eye' on the Diagnosis of Internal Disorders in Persimmon Fruit.

Recent rapid progress in deep neural network techniques has allowed recognition and classification of various objects, often exceeding the performance of the human eye. In plant biology and crop sciences, some deep neural network frameworks have been applied mainly for effective and rapid phenotyping. In this study, beyond simple optimizations of phenotyping, we propose an application of deep neural networks to make an image-based internal disorder diagnosis that is hard even for experts, and to visualize the reasons behind each diagnosis to provide biological interpretations.

Hand motion recognition based on forearm deformation measured with a distance sensor array.

Studies of upper limb motion analysis using surface electromyogram (sEMG) signals measured from the forearm plays an important role in various applications, such as human interfaces for controlling robotic exoskeletons, prosthetic hands, and evaluation of body functions. Though the sEMG signals have a lot of information about the activities of the muscles, the signals do not have the activities of the deep layer muscles. We focused on forearm deformation, since hand motion brings the muscles, tendons, and skeletons under the skin.

Novel neurotrophic phenylbutenoids from Indonesian ginger Bangle, Zingiber purpureum.

Two new curcuminoids 1 and 2, and a new phenylbutenoid dimer 3, were isolated from Bangle (Zingiber purpureum). Their structures were determined on the basis of comprehensive spectroscopic data and their biogenetic pathway. Compounds 1 and 2 are the first example of curcumin coupled with phenylbutenoid.
